The Blackberry Torch smartphone belonging to Vybz Kartel was allegedly used to make calls and send text messages while in police custody.

The phone contained text messages, voice notes and other multimedia evidence the prosecution presented in the trial.

“The integrity of the phone was compromised between the 3rd and 22nd of October [2010],” the judge said.

Detective Sergeant Patrick Linton admitted that he left his locker keys on top of his locker and the phone got compromised by someone inside his department at the Cybercrime unit.

Justice Lennox Campbell also told jurors that they should determine if police corruption supports the defense arguments that the police fabricated evidence to secure a conviction in the case.

Vybz Kartel, born name Adidja Palmer, and his co-accused Shawn “Storm” Campbell, Kahira Jones, André St John, and Shane Williams are on trial for the murder of Clive “Lizard” Williams, who authorities say was killed on August 16, 2011 in Havendale over two missing guns.
